Aberration Correction

Definition

Aberration correction refers to the process of reducing or eliminating optical aberrations in imaging systems, which can distort images and affect the clarity and accuracy of visual data. In the context of computational displays, this technique is vital for enhancing image quality, ensuring that the final output is sharp and true to the original scene captured by the camera or sensor. By utilizing algorithms and advanced optics, aberration correction optimizes visual experiences across various applications, including virtual reality and augmented reality.
